AIteferring to t-hedrawihgsiinsdetailfpairticularly Figures-l to E'5j inclusive, there is disclosed 4one conception-*fof l'a' `sacking apparatus constituting the'fpresent "invention, which comprises a stand frame-designatedgenerallyiat A, involving ahorizontall-lyfdisposed boarded platform sIl carrying sled-Jlilre'underslung 'runners "I "I .supporting the frame-Adri 'afperpendicularposition. 'Rising from therplatform "I 0 yarethe latticedvertical 'sideiwal's P2 twhichiextend'"upwardly asuniformdetermined height with cross joists I2' capping the frame A at the top thereof, these joists being joined with the walls I2 in any selected manner to eifect rigidity' to such frame.

Centered within the frame A next to the front thereof is a vertically disposed sack former I3, in this instance of cylindrical shape, yet it may be of another cross-sectional contour, having horizoritally swinging double doors I4, hinged at I5 for access to the interior of the former through the front of the frame A. The former I3 is held in a xed position by vertical studdings I6 built in the Walling thereof rising from the platform II) to an upper iioor I1 horizontally built in the frame A with the upper open end of the former I3 cleared therethrough.

Adapted to be suspended within the former I3 is a bag or sack I8, which has its upper open end portion removably fitted over a shaping hoop or ring I9, about which is overlapped this end portion of the bag or sack and fastened to this ring I9 by a clamping band 20, as best seen in Figure 3 of the drawings. This bag or sack I8 is thus suspended within the former I3 and when so located it is lled with libre materials, such Vas fleece, wool or the like, as hereinafter described.

At the front of the frame A next to the former -I3 is arranged a horizontally swingable outwardly bulged gate 2i, its hinges being indicated at 22, while at 23 is a release latch for fastening the said gate closed. This gate 2| when opened gives access to the former I3 at the doors i4 thereof; 5-

which when opened allow of the removal vof a l lled bag or sack I 8 from such former by hand.

The studdings I6 are extended upwardly closev to the cross joists l2 capping the frame A and above the floor I'I to provide a runway and trackage 24 for a weighted movable tampering body 25 which in this instance is of barrel shape, yet it may be otherwise shaped, and such body is raised and lowered by a block pulley and cable 26 and 27, respectively hoisting assembly, the cable 2l being operated driven from any suitable source of driving power not shown. The body when lowered in the runway 24 which leads to the former I3 tampers the material deposited within the bag or sack I8 confined in the former i3, the deposit of the material into such bag or sack being had from the oor I'I and can be hand or otherwise delivered.

In Figures 6 and 7 of the drawings there is shown a modification of the invention, wherein the stand frame 29 which is of the construction as shown, is supported on castor wheels 2l, so that the apparatus is rendered portable while the block pulley and cable assembly 28 for raising and lowering the tampering element 29 is operated through the cable by a windlass 30 having driven connections 3l with an electric motor 32 of the rotary driving type and supported in the frame 26.

In Figures l1 and 12 of the drawings there is shown another modication of the inven'ion, wherein the apparatus is rendered self-contained and mobile. In lieu of mounting the stand frame 26 on castor wheels 2l', the frame can be supported for towing to a desired place of operation. As shown in Figures llvand l2, the frame 33 of the apparatus carries running gear, including the traction wheels 34, and a trailer hitch 35 respectively. This frame 33 has a foldable crane assembly 39 for the cable of the hoisting assembly.

In lieu of the pulley arrangement of Figures 1 to 7, inclusive, for raising and lowering the tampering body 25 or 29, alternative forms cf mechanical movements may be substituted. For

4 example, as shown in Figure 13 of the drawings, which is a further modification of the invention, the tampering element 31 is drivenl by a feed screw 28, actuated by driving gearing 39.

In Figure 14 is lshown another modification, wherein the tampering element 40 is operated by a telescopic hydraulically driven plunger 4I. Then in Figure 15 of drawings, is shown an additional modiflcation, wherein the tampering element 42 is driven by a toothed rack and pinion assembly 43 and 44 respectively.

lIn Figure 16 of the drawings there is shown a modified form of bag or sack former 45, this being .only one example 0f a build thereof for use in the apparatus.

i What is claimed is:

n In a machine for filling sacks comprising in combination a supporting structure, a plurality of upright members extending from said supporting structure, an arcuate wall portion attached to and extending from each side of one of said upright members, complementary arcuate door por-v tions pivotally mounted on said arcuate wall portions, respectively, said wall and door portions constituting a sack former, a substantially V,- shaped gate pivotally attached to another of said upright members and adapted to engage said door portions for simultaneously closing the same on said arcuate wall portions, latch means on another of said upright members for releasably engaging said gate for holding the same, and therebyithe door portions, locked, means on said wall and door portions for holding a sack suspended within the sack former whereby said sack can be filled with material, guide members above and aligned with said sack former, a tamping weight slidably received by said guide members whereby said weight is directed into the sack former for compressing the material within the sack and means carried by said supporting structure for lowering said weight into and withdrawing the same from said sack former.
